--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think lowering LDBL_MAX_EXP would be far worse than this.
The double-double format is unusable for any real numerics in so many ways that
this is just one small part of that, the variable precision from 106 to
thousands of precision bits depending on exact value is far worse.
